Application April 6, 1938, Serial No. 200,336

(,Cl. 21S-54) 14 Claims.

My invention relates to a labeling machine. Reference is hereby made to my co-pending applications Serial No. 131,273, filed March 17, 1937, and Serial No. 149,123, filed June 19, 1937, for subject matter shown but not claimed herein.

An object of the present invention is to prevent the transfer of a label from a stack of labels to a container support, in a continuously running machine, when a container is not disposed in position for a label.

Other objects are to provide an auxiliary means to press the labels against thecontainer, to insure that the label is firmly aifixed thereon, and to prevent the actuation of such mechanism when no container is disposed for such auxiliary pressing step.

Still another object is to provide means to apply adhesive to the center portion of the labels.

A further object is to provide means to apply adhesive to the recesses on the rear face of an embossed label.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description.

In the drawings, like reference characters designate similar parts in the several views.

Referring more in detail to the drawings, the reference numeral I5 generally designates the framework of my labeling machine. The two motors, I6 and Il, are mounted on the framework. Motor |6 is the prime mover for driving the major portion of the operating mechanism of the machine, while the motor Il is to drive the auxiliary pressing mechanism. A rod I8 braces the motor Il on an upright member on the framework. The brace rod I8 is shown broken away in Figures 1 and 2, for the purposes of clarity, but in reality connects with beam I9 ofV the framework |5.

A flexible drive cable 20 is driven by the motor 1.. A manual switch 2| controls vthe motor Il. A pinion gear 22 is driven by the iiexible drive cable 20. A train of gears 23, 24 drive a rotary brush 25 upon which the gear 24 is mounted. 'I'he train of gears and a gear 26 are driven by the driving gear 22. A brush 21 is driven by the gear 26. The brushes and gears are mounted on a swinging carrier 28. The carrier has arms 4| and 42 between which brushes are mounted. The brushes are rotated to wipe a label outwardly.

A rotary table 29 carries stalls 30 provided with converging spring lingers 3| that grip bottles in the stalls. A shaft 32 has mounted thereon a finger 33. The shaft 32 is rotatably mounted in a bearing block 232. The shaft 32 extends ver- -tically alongside the rotary table 29. The linger 33 overhangs the table, when there is no bottle in the stall opposite the rotary brushes. The shaft 32 and table 29 each rotate about its own central axis. A crank arm 34 on the shaft 32 carries a finger 35 that rides in a slot 36 in a plate 3l pivoted on a rocker shaft 40. A spring ger is thereby moved to the full line position of Figure 5. This movement of the nger 93 rotates the shaft 32 in the direction of the arrow of Figure 6. Of Icourse the crank arm moves'in a clockwise direction too. The finger :l5V thus moves the plate 31 toward the broken line position of Figure 6.

The plate carries an adjustable stop 44. When the plate 31 is in the full line position of Figure 6, the stop 44 is engaged by an abutment 45 that is mounted on an arm 46 on the rock shaft 49. When the plate is moved to said broken line position, the stop 44 is thereby moved to its broken line position, also shown in Figure 6. The abutment 45 is thereby released, permitting the shaft 40 to rock. When the shaft 40 rocks, the brush carrier moves the brushes 25, 21 toward the adjacent container, to provide an outwardly wiping action upon the label thereon.

The mechanism to rock the shaft 49 includes a lug 41 pivoted on an arm 48 on the shaft. .A pin 49 is slidable lengthwise through an aperture in the lug 41. The pin 49 has an eye connection with a crank arm 59. Coiled springs 5| and 52 are provided on the pin at either side of the lug 41. Abutments 58, 54 on the pin 49 limit the longitudinal movement of the springs on the pin. By means of this resilient connection, the crank arm 59 may rotate continually and the pin 49 may reciprocate longitudinally in a continuous operation, but the shaft 49 is not thereby rocked unless the stop 44 is removed from the path of the abutment 45, and the stop 44 is only removed from said path when a bottle is not in the stall opposite the brushes.

The crank arm 59 is driven by a spindle 55 carrying a bevel gear 5S. A bevel gear 51 meshes with the first-mentioned gear 56 and in turn is driven by a sprocket 58 and chain 59. The chain 59 is driven by a small sprocket 69 on a countershaft 9|. A larger sprocket 62 on the same shaft is driven by a chain 63, which in turn is driven by a small reduction sprocket 84 on a stub shaft 65. A larger sprocket 56 on the latter shaft is driven by a chain 61 on the motor I8.

The spindle 55V not only drives the crank arm 50, but also operates a Geneva -drive for the table 29. Said drive comprises a disk G8 rotatable by the spindle 55. A tooth 99 on the disk successively gears with slots 19 in a star disk 1| on an arbor 12. .A bearing 13 mounts the arbor 12 on the framework I5 of the machine. It is to be understood that both the star disk 1| and the table 29 arekeyed to the arbor 12.

The tooth 99 revolves continually and upon each revolution advances the star disk the distance between two of the slots 19. The number of the slots 19 corresponds with the number of stalls 39 on the table 29. Thus the stalls are successively presented to the label applying means and the brush wiping means. The Geneva drive operates the table in a direction in which the stalls are presented to the label applying means `the shaft 11 turns.

lthe edges of the label are curled back. l. A crank 18 on a projecting end of the main shaft 6| drives a crank 19 on a projecting end of the shaft 11 by means of a connecting rod 80. By this operating mechanism, the picker bars are reciprocated between a position in which they present a glued label to a bottle and a position in which they withdraw a bottom label from a stack of'labels 8|. The full line position of the picker bars in Figure 2` shows the former position and the position of the picker bars in Figure 7 shows same approaching the label stack.

The Vlabel holder is generally indicated by the reference number 82. It is believed that further details of the label holder are not necessary here, since they are described and claimed in-my said co-pending application Serial No. 149,123.Y

The present label holder, however, isv mounted on -a frame 83 pivotedon the main framework of the machine by means of the shaft 11. 'Ihe frame 83 is suspended by springs 84 from brackets 85 on the main framework.

To cause the label holder frame 83 to move down to a position in which a label may be removed from thesupply, ears 81 fastened on the shaft 11 engage a member of the frame 83 as This engagement causes the frame 33 to swing downward about the shaft 11 as an axis. This swinging movement is effected ,during each cycle of operation ,of the machine,

but it will be noted that this downward swinging movement of the frame 93 is effected only at a time when the pickers are not near the label supply. When the shaft 11v turns, to raise the pickers toward the label supply, the ears 81 are swung away from the frame 83, permitting said frame to be lifted out of the path of the picker bars by means of the springs 84.

In order to maintain the label supply within the limits of the path of the picker bars, when there is a container to be labeled, a lever 88 that engages the container is swung to the right in Figure 5 about pin 89 as an axis. Of course when there is no `container in the stall opposite this lever, such swinging movement is not effected. However, when there is a container present, this swinging movement of the lever 88 is effected, which causes a bell crank 99 to produce longitudinal movement of a rod 9|. A crank 92 at`V the opposite end 'of the rod 9| is pivotally mounted on a bracket 93 on the framework. An upright shaft 94 journaled on the bracket 93 is keyed at its lower end to the crank 92, whereby rocking motion of the crank is imparted to the shaft.

The upper end of the shaft 94 also carries a crank 95'. The crank 95 engages a roller 96 on a slide rod 91. Rocking motion ofthe shaft 94 thereby Vcauses the countershaft 91 to move longitudinally. Helical springs 98 and 99 tend to balance the slide rod 91 at what will be called a restlposition. Guidesl and |9| tend to compress said springs respectively against bearings |02 on the sides of the main framework, when the rod 91 is moved out of said rest position one direction or the other.

In the said rest position, a latch |03 on the label carrier frame is out of vertical alinement with an abutment |04 fixed on a bar |05, which is parallel with the slide rod 91. An adjustable stop |06 on an oiset arm |01 on the bar |05 limits upward movement of the label carrier frame. The abutment |04 also straddles the bar |05, as shown at |08, to prevent turning movement of the abutment on the rod 91.

When rocking of the crank arm 95 moves the rod 91 (upward in Figure 8), the latch |03 is moved under the abutment |04, as shown in Figures 10 and 11. The label carrier frame is thus locked in its lowered position, whereby the picker bars may engage the bottom label of the stack and remove same from the label carrier for conveyance to a container. It is to be understood that the latch |03 is only locked down when there is a container at the station previous to applying station that will be ready to receive a label.

A manual switch |09 is arranged on the framework for controlling the motor I6.

.A source of adhesive is provided in a glue reservoir supported by a U-shaped bracing member ||0. A continuously driven roller ||2 lifts films of the adhesive above the body thereof. The roller ||2 is suitably driven by a sprocket ||3 and a chain |4. The chain is in turn driven by a sprocket on the shaft 6|.

An adhesive applying roller ||6 mounted on an arm ||1 on a shaft H8, which shaft is supported on a bracket H9, swings from a position of contact with the reservoir roller ||2, as shown in Figures 'l and 9, to a position of contact with the picker bars, as shown in Figure 2, from which position it is ready to roll along and thus apply adhesive to the picker bars.

'Ihe swinging movement of the roller 6 from the position shown in Figure 2 to engagement with the glue reservoir roller ||2 is produced by the upward swing of the picker bars. The return movement of the roller ||6 from engagement with the reservoir roller 2 to the position shown in Figure 2, is effected by a coil spring |20 which was placed under tension by movement of the roller I6 from the position of Figure 2 to engagement with the roller ||2. A dash-pot |2| dampens the release of tension in the spring |20 and hydraulically resists movement of the roller llt` in either direction. The spring |20 is connected to a stationary part of the main framework and to an arm |22 fastened on the shaft ||8.

To maintain the rollers ||2 and ||6 in contact with each other yduring the movement of the picker bars from the label stack to the container, a pivoted latch |23 is hooked around an end of a trigger arm |24, which is also fastened on the shaft ||8. A spring |25 tends to hold the latch |23 in engagement with the arm |24. An ear |26 on the latch is disposed in the path of a head |21 of the crank 19. Thus upon the descent of the head |21, it strikes the ear |26, releasing the trigger arm |24 from the latch |23, permitting the roller ||6 to swing forward to the position shown in Figure 2, under tension of the spring |20.

After the label has been carried to the container by the picker bars, an oscillating finger |28 that is mounted on a shaft |29 swings into the space between the picker bars 14. A crank |30 on the shaftl |29 rocks said shaft and also the nger |28. i A coil spring |3| connected with the crank |30 tends to move the nger |28 away from the container table 29.

The outer end of the crank |30 has a sliding connection with a longitudinally movable bar |32. A spring |33 cushions the relative movements of the crank and the bar. The bar has a slot |34, wherebythe bar is slidable on the shaft 6|. The bar carries a roller |35 which rides on a cam |36 also on the shaft 6|. Thus rotation of the cam |36 in the direction of the arrow on same causes the bar |32 to move the finger |28 into engagement with a label'on a container. The spring |33 causes such engagement to be a resilient one. The linger |28 is also preferably padded.

The label applying means comprises rails |31 swinging on a spindle |38 on the main framework. A carriage |39 slides forward and backwar-d on the rails. A head |40 on the carriage has cushion rubber pads |4|4 that engage the label at either side of the finger |28 and urge the label into a close aixed position on the container.

The carriage |39 has a cam |42. A roller |43 is mounted on one of the rails |31. Stop |99 limits upward movement of the carriage |39. Downward movement of this carriage is limited by the cam |48 and roller |43. The roller |43 is on one of the 'slide rails and to the rear of the carriage. Return springs |44, |45 tend to produce rearward movement of the carriage |39 on the track. Forward movement of the carriage toward a label pressing position, against the tension of the springs |44, |45, is eiected by an arm |46 fastened on and rotating with the shaft 6|. An anti-friction roller |41 on the end of the arm |46 directly engages the cam |42 during rotation of the arm.

While a label is being transferred from the `stack to a container, the carriage |39 and track |31 are in its lowered position, shown in broken lines in Figure 2. After the picker bars have delivered a label to a container and have moved upwardly, the Vtrack |31 and carriage 39 are swung upwardly to a horizontal position, as shown in Figure '1. This upward swing is effected by a cam `|48 also on the shaft 6|. This cam |48 engages the roller |43.

Means for supplying adhesive to labels comprises opposed guides |49,`in which slides an axle |50 of acenter gumming roller |5I. Link means |52 connects the arm ||1 with the axle |50, whereby reciprocating movements of the arm ||1 are communicated to the center gumming roller Y| 5|. Slide or guide members |53, freely pivoted on the axle |50, slide along the label as it is being gummed. The slide members prevent the label from following the roller, since they extend laterally beyond the roller in a plane parallel with the rear face of the label. |54 extends down Vto the bottom ofthe label stack on the side first engaged by the center gumming roller |5|. This arrangement prevents the roller from applying adhesive to the edge of the stack. The stack is raised on the return movement of the roller |5|, thus avoiding the gumming of the opposite edge of the label stack.

It is to be noted that the center gumming mechanism applies adhesive to the bottom label while it is still in the stack,and that the mechanism is so timed that said label is not gummed when there is no container ready to receive it,

A guard since the carrier moves out of the-path of the roller |5|, by the mechanism described.

It is preferred to have a nal pressing mechanism, to press labels against the containers. This is especially desirable for a varnished label. It is also desirable to have this final pressing exerted with considerable pressure.

To eifect this, a pneumatic cylinder |65 is supported on a shelf |66 opposite stalls 30 on the platform 29, by means of a bracket |61. A piston |68 in the cylinder drives a piston rod |69. which in turn carries a head provided with a sponge rubber cushion |1| that engages and presses the label rmly against the opposed bottle |12. Helical springs |13 at either side of the cylinder |65-connect the head |10 with the bracket S1. These springs cause the withdrawal of the rubber cushion from the bottle when the air pressure is released in the cylinder |65.

An air line |14 supplies air pressure from a source (not shown). supplies air pressure to the pneumatic mechanism at a constant rate. A gauge. |16 is arranged in line |11 leading from the regulator or reducer.

The line |11 directs air pressure to a xed member |18 of a sliding valve |19. The sliding i of the arm |85 causesthe passage |82 of the sliding valve member to move from a position in register with the passage |83 to a position in register with the exhaust passage 94.

A cam |81 is preferably disposed on the lower end of the spindle 55. Rotation of the cam |81 causes the arm |85 to move from the full line to the broken line position of Figure 20. The spring |86 causes the return of the arm. The cam |81 directly engages a roller |88 on the arm |85.

The conduit |8| in turn connects with a valve |89. A pipe |99 connects the valve |89 with the head` of the cylinder |65, to supply air pressure to the interior thereof ahead vof the piston |68. A spring |9| connects with a lever |92 that operates the valveY |89. The spring 9| tends to maintain the valve |89 closed.

To open the valve |89, a linger |93 is mounted on the shaft 32, and a connecting rod |94 con- A regulator or reducer The member |18 also has an exhaust nects the lever |92 with an arm |95 on the shaft 32. When the nger |93 is moved by a bottle |12 in the stall opposite the cushion 1|, the shaft 32, arm |95, connecting rod |94 and lever |92- open the valve |89. If no bottle is present |9| maintains the valve |89 closed.

It will be noted that the fingers 33 and |93 engage the neck of the bottles. Since there is less variation in the position of the necks of 1n the stall opposite the cushion the sprmg different bottles than in the outside diameters Y Asthe platform or table 29rotates, theoperator places bottles or other containers-in the stalls 30. Bottles |55 are shown in the drawings.

As the stalls carrying containers pass the lever 88, the rod 9|, crank 92and associated mechanism cause the countershaft 91 to move longitudinally thus bringing the latch |93 under the abutment |04. The label carreris thereby locked in its lowered position, whereby the picker bars 14, 15 may remove the bottom label from the stack on the next reciprocation of the picker bars.

Thereupon the picker bars 94, 95` carry the label down to the container. The nger |28 is then raised, holding the center of the label against the container. 'I'he picker bars then move upward away from the label, allowing the ngerY |28.to hold the label in place. Upward movement of the picker bars causes the gumming roller H5 to roll across the sponge rubber pads on the picker bars, whereby to apply adhesive to the pads for the next label.

Rolling of the gum roller IIS across the pads 16 causes the arm` ||1 to swing said roller into engagement with the glue fountain roller ||2 for a fresh supply of glue.

The center gumming roller |5| has previously been rolled across the bottom label of the stack by reason of the reciprocation of the arms ||1.

After raising of the picker bars, the rails |31 andcarriage |39 are swung to a horizontal position and the carriage |39 propelled forward to its broken line position in Figure '1. The pads |4| on the carriage press the label securely on the container. Upon withdrawal of the carriage, the table or platform 29 is again intermittently rotated by the Geneva drive hereinbefore described.

The container then engages the nger 33, which causes the brushes 25, 21 to move against the label and wipe same outwardly, to rmly aix the label.

Upon the next intermittent movement of the table, the labeled container is ready to be removed and replaced by a container to be labeled.

In the operation of the pneumatic label pressing mechanism, a continual supply of air pressure is provided in the line |14. While the machine is operating, the sliding valve |89 is continuously opening and closing. However, this does not permit' air pressure to flow into the cylinder |55 until the valve |89 is opened by a bottle opposite the cushion |1|.

When both valves |19 and |89 are open, the pressing action'of the cushion upon the label is quick, hrm and positive, thus insuring a close contact of the label upon the bottle. The springs |13 withdraw the cushion for the next bottle.

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to jmodications without departing from the spirit of my invention.
